| Abstract: | On the basis of small photovoltaic system connected to lowvoltage grid, this paper added the lithium-battery energy storage device and operating the micro-grid combining PV and energy-storage according the local load. The PV inverter unit takes the Vdc-Q control strategy. Bi-directional converter used in energy device takes PQ control strategy in grid-on mode that the power reference value was determined by the power control module of tie-iine. By analyzing the operating characteristics of micro-grid in grid-on mode when the load is changing rapidly, the paper verifies correctness and effectiveness of the control strategies of microgrid. |
